26 Claims. (01. 123-8) This invention relates to prime movers in which central partition; the showing extends over two the static or dynamic energy contained in a fluid revolutions (720) in which said channels pass is transferred into mechanical energy of rotation, thru one convolution. compressors or .pumps in which that process is 5 reversed, and also to prime 'movers adapted tomake use of the dynamic energy created by the scombustion of fluids.'

The primary object of our invention has been to provide positive acting, rotating means for the creation, conversion or utilization of energy.

Another object of this invention has been to provide a uniform, unidirectional speed of movement of all the moving parts of such an engine,

such speed of movement being predeterminedly 15 related to the speed of movement of the part fromwhich the energy is finally transmitted for use.

Other objects of our invention will be brought forth in the exemplary description and drawings 20 which form part of this patent application.

,In developing our invention we make use of a chamber comprising two similar channels which are helically entwined in a circle along a substantially circular path, the chamber being to- 5 roidal, and the channels are sub-divided by a partition which centrally extends through said spirally disposed channels 'The partition establishes part channels in the helical channels, which increase and decrease peripherally, whereas a 30 transversecross-section of said combined helical channels remains substantially the same. A body, piston, or disc, subeilantially of the shape of said cross-section, is propell'ed through said helical channels by the force of movement or of part of the engine of Fig. 9. The central partitionis omitted.

It relates to intercommunicated halves of each twin part of said engine.

Figs. 32 and 33 illustrate in sectional detail front and side views, respectively, the valve gearing of the engine of Figs. 28, 29, 30, and 31.

The engine shown in a sectioned side elevation in Fig. 34 represents a mechanically reversed modification of the arrangements of Fig. 9.

The housing of Fig. 9 comprises similar front and back halves 4| and 42, which are bolted together. The housing centrally supports a shaft 43, upon which is mounted a substantially flat,

. concentrically disposed partition 44, said partition being fixedly mounted upon and adapted to revolve with said shaft. The partition 44 extends substantially centrally through the cylindrical annulus or toroidal chamber 45, the walls of which are formed by the front 4| and the rear 42 of the housing of the engine. Concentric with annulus 45, substantially half round lugs 46 and 41, (complementarily forming a tore) extend from the front and from the rear of partition 44.

From opposite sides of the annulus the two walls 48 and 49 which form continuation halves of a helically disposed dividing wall radially extending into the annulus, substantially into sliding abut- 1 ment with the lugs 46 and 41. The walls 48 and 49 pass through half a convolution along the full circular extent of the annulus so that the pitch of the respective helix is twice the circumference of the pitch circle of 'said annulus.

The partition 44 is provided with a radially disposed slot of a length substantially equal to the diameter of the cylindrical annulus. In that slot is rotatingly slidably accommodated the disc 50. The thickness of disc 50 is such, that it slidably abuts upon the sides of the slot in partition 44 and .its periphery is engaged in slidable abutment upon the inner walls of the cylindrical annulus 45. The disc 50 is provided upon opposite sides with truncated sector openings 5|, which extend-into the disc up to the diameter of the half round lugs 46 and 41, and which slidably accommodate the helical walls 48 and 49, respectively. The disc 50' is carried through the annulus by the rotating partition 44 and it is angularly guided by the walls 48 and 49. When the shaft 43 together with the partition 44 makes one revolution, the disc 50 will therefore rotate around its own axis through half a rotation, in conformity with the pitch of the helically disposed walls 48 and 4 9.

The partition 44 extends in slidable abutment through the walls of the cylindrical annulus 45 and through the helically. disposed walls 48 and 49, where it merges therewith. When the disc 50 is disposed at the position of Fig. 9, which would be in close proximity ..to the point at which the cross-section of Fig. 7 is taken, the cylindrical annulus is subdivided into four substantially closed chambers 52 and 53, 54 and 55, the first pair in front of partition 44, the second pair in the rear of said partition. The chambers 52 and 53, and 54 and 55, are respectively continuations of each other on the respective sides of the partition, but they are respectively separated from each other by the parts of disc 50 extending to the front and to the rear through partition 44. When the disc 50 is disposed in the-lowest part,of the, cylindrical annulus and at a position near the cross-section of Fig. 1,. there are only two chambers in the annulus, one-to the left and one to the right of partition 44, because the helically disposed walls 48'and 49 merge with the partition 44. at that point.

counterclockwise direction.

To the left of that position, the chambers 53 and 54 develop in the front and in the back of par- I the position of Fig. 1, and following the cylindrical annulus, in clockwise direction, the cross-sections of Figs. 2, 3, 4, 5, 6, 7 and 8 show the annulus 45, 225, 270, and 315,respectively, away from the position of Fig. 1 and viewed in a Let us imagine that during the clockwise rotation of shaft 43, the-disc 50 is just ahead of the various cross-sections of said figures, i. e., has just past the positions of said cross-sections. Into the developing chambers 53 and 54 steam is inject-ed, exemplarily at the point of the cross-section of Fig. 2, through inlets 56 and 51, respectively. The helical walls are stationary. The partition 44 is movable, but not in respect to the chambers contained in the annulus: in respect to those, it is relatively stationary. However, the part of disc 50, which closes said chambers in a clockwise di- .now begins rearwardly to shorten the length of the chamber containing the steam, having again entered upon chamber 54, and the source of steam is shut off, after the disc has passed the inlet 5| of Fig. 2. When the disc now reaches .for a second time the position of Fig. 5, we have passed through 540 and the volume of the steam in-the chambers 54 and 55 has now reached a maximum,-

as can readily be seen from the diagram of Fig. 10 l which shows the developed chambers54 and 55 to the rear of the partition 44.

In Fig. 10 the substantially sinusoidal curve represents the convolution of the helically disposed wall from 0 to 360, between 360 and 720 it represents the wall 48, the respective positions of said walls having been exchanged at 360. The disc 50 is shown in the position of Fig.- 5, i. e., at 180 and 540. The steam chamber, development of which we have observed, extends therefore between 180 and'540, laterally confronted by the disc 50, and upwardly confronted by the'sinusoidal curve. It has attained its largest volume and slightly decreases in size, as the disc advances I to the 675 position, in which the chamber 55 has shrunk to a very small cross-section. After the partition has passed over the outlet 59, said outlet becomes connected to the steam chamber, the development of which we have followed, and the disc 50 pushes the steam out of said outlet, as it passes from the 315 position to the 675 position,

' it then passes to the 720 or 0" position.

The steam inlet 51 is shown in the top view of Fig. 11 between the groove 58,into which the partition 44 slidably extends, outwardly from the concentric annulus 45,-and the'helical wall 49. The outlet 60 in the steam chamber 52 at the of valve 6| extends through the front 4| of th housing, and is there provided with a hand wheel 54, by means of'which thev'alve may be set in positions of forward and reverse rotation of the engine. In the forward position-of Fig. 12, the steam supply is connected from conduit 52 through valve 61, to a manifold 65, which is branched off at 66, one branch connecting through conduit 61 to the inlet 51, whereas the other branch 58;(which is shown in Fig. 9 but notin Fig. 12) passes through the front 41 of the housing upwardly to a point above the lower extent of the annulus 45, to the inlet 55. The conduit 63 connects in the position of valve 6| of Fig. 12 to the manifold 69. One branch extends from manifold 69 to the outlet 60whereas the other branch 1| extends through the rear 42 of the housing to the outlet 59. Reversal of valve 6| will connect conduit 63 to conduit 65, and conduit 62 to conduit 69, so that the inlet and outlet parts of the engine are reversed; the engine will therefore rotate in anopposite, counter-clockwise direction.

If the expansion of the fluid, for instance compressed air or steam, is to be made use of, it is advisable to shift the outlet 59 to the position 15, as indicated in dotted lines in Fig. 10; or the outlet port 15 may be provided in addition to the outlet 59. In that manner, the fluid will be released from the chamber after it has reached 30 ,maximum expansion, which is at the 180, 540

position of the disc. When a port 15 is provided,

the engine can pf course not be reversed without further arrangements. To those acquainted with this art it readily suggests itself that're- 35 versing may be brought about by providing at corresponding points of all chambers similar ports 15 which may be selectively controlled by valve 5|.

If an inexpansible fluid is used forthe operation of our engine, water for instance, provisions have to be made to prevent a counteracting, undesir-v able vacuum,,between the 360 and 540 positions, during which period the chamberenlarges without being connected to any ports. This may I 45 be readily brought about by providing a poppet valve 16 at the 360 position, through which air or any other fluid may enter upon the chamber during the period of expansion. Undue compression of the inexpansible fluid inay be prevented by the auxiliary port 15.

Our engine has been described up t6 this point,

as a prime mover. In the same manner in which a reciprocating engine may be readilyconverted into a compressor or a vacuum pump, ou-r engine 55 may be converted for such purposes.

. The four chambers of our engine perform the work which is ordinarily performed by the four cylinders of an ordinary engine. The chambers 52 and 55, and 53 and'54, on either side of the 60 partition, respectively, are parts which simultaneously perform like work. In that manner the pressures applied to the disc upon both sides of partition 44, are balanced against each other,

so that the partition together with the lugs 46 andv 41 readily supports the disc in a transverse position. If the disc is well lubricated or is made of self-lubricating material, it will therefore float without trouble in the exact path ascribed to it.

To avoid excessive friction, we may'however 70 provide anti-friction means. Thus we exemplarily show a journalling of the disc in Figs. 15 and 16. The disc 80 of those figures is supported by twoball bearings 8| and 82, which are-journalled upon the lugs 46 and 41' of partition 44,

35 slightly outside of pitch circle of the annulus so that the axis of the disc 80 is tangential to that circle. The ball race of bearing 8| has'an outwardly threaded plug 83, which'is engaged by a nut 84. The plug 83 is non-rotatively slidably arranged in the directionof the axis of disc 80; by being mounted upon a square lug 85. By rotation of the nut 84 the bearings of the disc 80 may be tightened up. The bearing 82 is respectively mounted in a transverse slide 81, which is set in a position of alignment with the partition by screw 88. After the screw has been removed, andrafter the nut 84 has been rotated so as to slide plug 83 back on lug 85, bringing the ball out of engagement with disc 80 the disc 80 together with the journalling means on the slide side may be completely slid out of the partition in a direction at right angles thereto.

Since the coacting parts of the chamber on the two sides of the partition do not at all times act at similar distances from the axis of the main shaft although they are subjected to similar loads at like times but since those loads are not applied at exactly the same radial distance from the axis of shaft 43, the partition 44 is at times exposed to lateral stresses which may be taken up by ball races 89 disposed near the outer periphery of the partition and embedded in the two halves 41 and 42 of the housing. In order to protect the ball races 89, circles of packing 90 are provided in the halves 4| and 42 of the housing, which separate those ball races from the cylindrical annulus, at the sametime preventing exchange of fluids between the two halves, into which the annulus is divide by the partition. Similar packing 9| is provide upon two halves 4i and 42 of the housing inwardly from the ann'ulus', this packing serving toprevent diffusion or leaking of the fluids contained in the annulus into the clearance space 92 between the two halves of the housing. Compression springs 93 are embedded in suitable holes of the halves of the housing and compress the packing 90 into engagement with the partition.- Exchange of fluids between the halves into which the annulus is divided by the .helically disposed walls 48 and 49 is prevented by packin 94, which .is pressed by sets of compression springs 93 into sliding engagement upon the half round lugs 46 and 41, and into abutment with the bottom of the truncated sectors in the disc 80.

In the sides of the slot in' the partition' we ro-- vide grooves facing the disc 80 and in these grooves are embedded packing means 95, which serve to seal the disc 80 against the partition.

The packing rings 96, 91, a pair of which is accommodated in a suitable groove extending around the periphery of the disc 80. and along the sides of the sectors, serve to separate from each other the chambers into which the annulus is divided by the disc. -The two parts 96 and .91

of each ring are provided with serrated partswhich are overlappingly engaged upon each other and which allow the ring to be pressed'into outward engagement with the cylindrical annulus by the pressure inthe chambers, the appearance of that ring changing under such pressure from the view shown in Fig. 18 to that of Fig. 17.

Our engine has up to this point been illustrated as means which are served by inlet and outlet parts which do not require any cyclically operated valves, (disregarding the poppet valve 16) A better use. of the kinetic energy of expansion stored in the steam may be brought about by providing mechanically operated valves, as indicated in Fig. 20. The showing of these drawings alsoserves to illustrate, that our helically disposed chambers do not necessarily have to aggregate 'complementarily to an annulus, but that they mayassume other forms in modifications which may be prescribed by particular circumstances.

In relationto the positions shown by the crosssections of Figs. 1 to 8, the showing of Fig. 20 may be compared with Fig. 2, the cross-section of that figure being viewed in the opposite direct on. 1

' The disc IOI of this modification has a substantially figure 8 shape, .each of the two en-- twined channels being substantially cylindrical. Though we here really have a double disc, a plate, the term disc" is applied, in order to provide uniformity of expression throughout the specification. The chambers are therefore formed by two. helically entwined rings or channels, each of which is cylindrical. A particular advantage of such a modification is oii'ered in respect to packing the disc. Fig. 21 shows the extremely simple packing ring, a pair of which is used in connection with one figure 8 disc MI. The ports 56 and 51 of this modification are provided with valves I03 and I04, through which the steam is supplied from manifolds I05 and I06. The valve stems extend through packings I01 and I08 to compression springs I 09 which force these valves into normally closed positions. The stems are engaged by angle levers I10, the free ends of which are provided with rollers III. The rollers III are engaged upon cams II2 on cam shafts I I3, said cam shafts beingpositively geared to the main shaft of the engine. The valves I03 and I04 are operated each time a disc IOI has passed the respective ports I05 1 and I06. They are then opened to admit the steam; after a predetermined time interval they are closed again, the admitted steam being allowed fully to expand in the enlarging chambers. In order to permit ready comparison between this engine, in which cyclically operated valves are used, and the showing of the preceding figures, Figs. 22, '23, 24, 25, 26, and 27 are ex- I ecuted in a manner similar to that of Figs. 1 to 8 and 10. These diagrams serve to illustrate that there may be a relative decrease of the pitch of the helix of the chamber as well as an increase in the number of discs used, without departing from the spirit of this invention; it is not possible to lay down a fixed rule for the arrangement and proportionate number and shape of these parts under all circumstances. In this particular instance we have adopted a ratio of 4:3 between 5 the number of interposed elements, half discs precisely speaking, to convolutions, of the helically entwined chamber; the showing of Figs. 1 to 10 shows that ratio to be 1:1.-

A fair efliciency is attained with the arrange- 30 ment of Figs- 22 to 27. It is understood that the discs must bespaced evenly and that the half convolutions of the spirally entwined channels must also evenly divide into the pitch circumfer ence or one revolution of those chambers. In the 65 degree to which the pitch of the convolutions of the helically entwined channels is decreased in relation to the pitch circumference of one revolution of the chambers, a morefavorable and more eflicient ratio between discs and full convo- 70 lutions may be adapted. Whereas the prior showing involved one dis and a helix of a pitch equal to twice the circumferenceof the'pltch circle of the helicallyentwined chamber unit, we here exemplarily show 75 two discs, and chambers which are disposed in a helix with a pitch equal to as of the pitch circumference of the entwined helical channels. In other words, whereas in the previous showings the entwined chambers pass, per revolution,

through half a convolution, and then endlessly merge with each other, the chambers of this showing pass through one and one-half convolutions for one revolution of the engine.

The diagrams 26 and 21' show the two halves into which the chamber unit is divided by the partition, but each of these halves of the unit is developed for only one revolution (360), whereas the showing of Fig. 10 extended over two turns, 720.

It will be seen that by this kind of an arrangement we obtain full expansion in the chambers. Valves I03 and I04 are indicated by the numerals H4 and H5 "at the positions of the discs in respect to the chambers at which said valves open and close. Between said positions of the disc steam is admitted and the shaded part of the chamber indicates to what volume the admitted steam has expanded, when the disc has reached the 180 position. While the disc moves on, fur-j ther expansion occurs, but near the end, before the disc II6 reaches the exhaust port II 1, the

second disc H8 is moved into the chamber and reduces the volume of the expanded steam for a fraction of the volume reached thereby at maximum expansion. Immediately thereafter the disc II6 passes the outlet (59) so that the disc I I8 now evacuates the steam from the chamber through that outlet.

It is seen from these diagrams that only a regulation of the inlet port by cyclically operated valves is necessary.

Figs. 28, 29, 30, and 31 exemplarily show how the principle of our invention may-be utilized for internal combustion motors. Two units I20 and HI are assembled side by side, substantially in parallelism, each of said units being independent, but the respective partitions I22 and I23 being mounted on a common shaft. The front unit I2I of the twin engine is the compression unit whereas the rear part I20 is the explosion unit.

The number of parts and the pitch of the helixcorresponds for each half I20 and I2I to the showing of Figs. 26 and 27. The three sets of chambers of the compression and explosion unit which face each other between the two units I20 and I2'I, are connected by conduits I24, each end of which may be closed by a cock I25; the pairs .ofcocks I25, in relation to said three sets of' chambers, are referred to in the drawings by indices a, b, and c respectively. The operation of these cocks is controlled from the main shaft of the engine by suitable, positive gearing. In a similar manner a conduit I26, which is provided with mechanically operated cocks I21, connects the chambers of the compression and explosion units, which are disposed outwardly from the two partitions I22 and I23.

The gearing by which the valves I25 and =I21 are operated, is shown in Figs. 32 and 33, the plane of the view of Fig. 33 being slightly angularly displaced'from the section of Fig. 28.

On the main shaft I6I is mounted the double cam I62. The rollers I63a, b and c, which are mounted upon the ends of the valve rods I64a, b and c are pressed onto cam I62 by the springs I65; these springs act thrustwise between the bracket I66 mounted on the engine housing and the shoulders I61.

The rods I64 radially reciprocate in, respect to shaft I6I and those movements are transmitted by links I68 to the double levers I69 on the stems of one set of cocks I21. By means of the connecting rods I10 an angular movement similar to that of double levers I69 is imparted to levers HI ,on the other set of cocks I21. The angle lever I12 is similarly actuated by rod I and the angular movement thereof is transmitted by links I13, slide rods I14, links I15 and levers I16 to the stems of cocks I25, so that each of the three sets 10 of cocks I and I21, which are angularly spaced 120 apart from each other, are predeterminedly cyclically opened and closed.

The discs I28 and I29 of the compression chamber and the discs I30 and I3I of the expansion 15 chambeiware relatively disposed in the manner shown in the diagram in Fig. 21. The same applies to the pairs of inlet ports I33, I and I31 on the compression chamber, and to the pairs of exhaust ports I38 and I39, I40 and MI, and I42 and I43, on the explosion chamber. Each pair of these intake and exhaust ports is angularly aligned. The firing takes place after the fully compressed charge has been transferred through conduits I24 and I26 from the compression unit 25 to the explosion unit, and after the cocks I25 and I21 had been closed. The pairs of spark plugs I44 and I45, I46 and I41, and I48 and I49, are respectively in angular alignment, at positions indicated in Fig. 30.- Cock I35b of Fig. 31 having 30 just been closedfspark plug I41 fires at the instant of observation. The spark plugs I45, I41 and I49, may be approached through suitable openings I50 and I5I in the wall of the rear part I20 of the housing and openings I5I in the partition I22.

The modification of Fig. 34 represents a re-,

versal of the arrangement of Fig. 9. The bracket I11 is stationary, and rotatably supports the shaft I18; which carries at one end the pulley I19 and at the other end the casing,I80 with the helically 40 entwined chambers I8I and I82. The partition I83 and the discs I84 are shaped similar to the partition I44 and discs I80 of Fig. 9; but whereas the discs I44 rotate around their own axis, said discs and the partition I83 are angularly fixedly 45 disposed in respect to the axis of shaft I18.

The steam is introduced by a conduit I85,a stationary coupling I86 upon the end of which is rotatably mounted upon the end of the casing I80,opening into a chamber I81, which is cen- 5 trally disposed in said casing. From saidcasingthe steam isintroduced into the helicallyentwined chambers at locations corresponding to the layout of Figs. 1, 2, 3, 4, 5, 6, 7, 8, the re-. spective conduits I88 and I89 being incorporated in the casing I80.

The steam outlet takes place through similar conduits, which lead into amanifold I90 in the casing. From said casing, the exhaust vapors pass through the shaft na to the outlet I9I.

G The action of this engine is equivalent to that of Fig. 9. It will readily be noticed that, when the pitch of the helically entwined channel is less than twice the circumference at the pitch diameter of the entwined channels, the inlet and exhaust may respectively be introduced through the stationary bracket I11, and the stationary partition I83, at points, where the helically entwined channels start to develop. I v
